How many times have you tried to delete a report and realized that it is used in Home... but you can't figure out which Layout or Custom Home it is used in? I've got a solution!
Step 1: Go to report builder, Right-click → Inspect → Select Network tab → Clear Network Log

Step 2: Search your report

Step 3: Select list → Click on the Preview tab → Expand data → Expand data again → Expand 0: → Go to the bottom and copy the usedIn id

Step 4: Pull a report from the GS Asset Usage Tracking object filtering by that id. Now you have the user identified!

Step 5: Use the new Ability for Admin to login as a User to delete the dependency
Hope this helps
